Abstract

A permeameter including a fluid control chamber, a permeability specimen area, and a first outlet from the specimen area measuring fluid as a function of a normal permeability of at least one specimen in the specimen area and a second outlet from the specimen area receiving and measuring further fluid as a function of a radial permeability of the at least one specimen in the specimen area.

Claims (20)

1. A permeameter comprising:

a fluid control chamber;

a permeability specimen area; and

a first outlet from the specimen area coupled to a first measuring device measuring fluid as a function of a normal permeability of at least one specimen in the specimen area and a second outlet from the specimen area coupled to a second measuring device receiving and measuring further fluid as a function of a radial permeability of the at least one specimen in the specimen area.

2. The permeameter device as recited in claim 1 further comprising a piston and a piston cylinder.

3. The permeameter device as recited in claim 2 wherein the piston is integrated with deadweight.

4. The permeameter device as recited in claim 2 wherein a bearing is connected to the piston cylinder.

5. The permeameter device as recited in claim 4 further comprising a diaphragm spring mounted on the bearing.

6. The permeameter device as recited in claim 5 wherein the diaphragm spring is a Belleville spring.

7. The permeameter device as recited in claim 1 further comprising a mount.

8. The permeameter device as recited in claim 1 wherein the specimen area further comprises a ring specimen area and a disk specimen area.

9. The permeameter device as recited in claim 1 further comprising a seal between the ring specimen area and the disk specimen area.

10. The permeameter device as recited in claim 1 further comprising a first flow measurer connected to the first outlet and a second flow measurer connected to the second outlet.

11. The permeameter device as recited in claim 10 where in the first flow measurer is a graduated cylinder.

12. The permeameter device as recited in claim 10 wherein the first flow measurer is a flowmeter.

13. The permeameter device as recited in claim 1 further comprising on/off valves enabling the running of individual normal and radial permeability tests.

14. A method for measuring the permeability of at least one specimen comprising:

providing the apparatus as recited in claim 1 ; and

measuring a normal and radial permeability of the at least one specimen simultaneously.

15. The method as recited in claim 14 wherein at least one specimen includes a ring and a disk specimen.
